【摘要】 由于摆动辗压工艺比其它塑性成形工艺更为复杂,其工艺设计的难度和工作量也较大。摆动辗压成形工艺CAD的研制主要是提高摆辗工艺的设计效率和精度。以节油器内花键套为对象,建立了预制坯的体积计算模型及其结构设计模型,确立了摆动模的设计模型和凹模的力学分析模型,给出了摆辗工艺参数和力能参数的设计模型。在此基础上对摆辗成形工艺CAD系统进行了结构分析和功能分析,实现了预制坯、摆辗模具和摆辗参数的计算机辅助设计,设计效率可以提高60%以上,废品率降低25%以上,并结合实例得到了满意的设计结果。更多还原

【Abstract】 For rotary forging process is more complicated than that of other plastic deformation processes,rotary forging process design is accordingly more difficult and of heavy workload.The design efficiency and precision of rotary forging process were increased by developing the rotary forging deformation process CAD system.According to the structure feature of saving-oil device gear,some volume calculating models and structure design models were built,rotary forging die design model and lower die mechanics analyzing model were established,and some technical parameter models and power parameter models were also given.On these bases,rotary forging deformation process CAD system structure and functions were analyzed,and computer aided design for prefab blank,rotary forging dies and process parameters were realized.The design efficiency was raised more than 60%,waste product was reduced more than 25%,and some satisfactory design results were obtained with an example.更多还原
